Understanding the mechanisms controlling forest carbon storage is crucial to support “nature-based” solutions for climate change mitigation. We used a dataset of 892 Atlantic Forest inventories to assess the direct and indirect effects of environmental conditions, human impacts, tree community proprieties, and sampling methods on tree above-ground carbon stocks. We showed that the widely accepted drivers of carbon stocks, such as climate, soil, topography, and forest fragmentation, have a much smaller role than the forest disturbance history and functional proprieties of the Atlantic Forest. Specifically, within-forest disturbance level was the most important driver, with effect at least 30% higher than any of the environmental conditions individually. Thus, our findings suggest that the conservation of tropical carbon stocks may be dependable on, principally, avoiding forest degradation and that conservation policies focusing only on carbon may fail to protect tropical biodiversity.

人类影响是热带森林碳的主要驱动力

了解控制森林碳储存的机制对于支持缓解气候变化的“基于自然”的解决方案至关重要。我们使用包含 892 个大西洋森林清单的数据集来评估环境条件、人类影响、树木群落属性和采样方法对树木地上碳储量的直接和间接影响。我们表明,与大西洋森林的森林干扰历史和功能特性相比,气候、土壤、地形和森林破碎化等广泛接受的碳储量驱动因素的作用要小得多。具体而言,森林内干扰水平是最重要的驱动因素,其影响至少比任何环境条件单独高出 30%。因此,我们的研究结果表明,热带碳储量的保护可能依赖于,
